The most important thing with regards to business continuity services is speed and quality of support when it is required.

I have been using Datto Siris for several years. We had purchased S3B2000 unit for a client to replace their older unit and upgrade to larger data backup. Datto provided 5 year warranty on the unit. However, when unit gave a problem and stopped backing up (unknown Software or hardware issue, Datto support unilaterally decided without any explanation that it is not in warranty because of it being on a UPS and UPS battery powered off. Can you imagine a connection without UPS? Also can you find a UPS whose battery does not die after several years? The support made us do hard power shut off of the unit several times but it did nit connect to the environment. It sounds like a defect in the unit, but Datto support came up with a unilateral decision, without any explanation that they do not want to honor the warranty. Very poor response by support ????

Best backup solution I have used. Ease of use in GUI, backup speeds, agent based backup, screenshot verification, cloud mirroring Quick restore times with lots of restore options.

Datto pushes the philosophy of Business Continuity, not just Disaster Recovery, and they provide it.
